Summary:To prevent a fixing device from being damaged due to an increase in temperature.SOLUTION: A fixing device according to an embodiment of the present invention is a fixing device 50 that, in a printing operation in an image forming apparatus 100, fixes an unfixed image on recording paper P onto the recording paper P between a rotatable pressure roller 530 and a fixing belt 510 that is in contact with the pressure roller 530 and driven to rotate, and comprises: a symptom detection unit 56 that detects a change in specific parameter to be a symptom of the occurrence of jamming of the recording paper P; and a fixing drive control unit 58 that, when the change in specific parameter to be the symptom of the occurrence of jamming is detected, stops the rotation drive of the fixing belt 510.SELECTED DRAWING: Figure 8 【課題】温度上昇によって定着装置が損傷することを防止することを目的とする。【解決手段】本発明の一実施形態に係る定着装置は、画像形成装置１００における印刷動作において、回転可能な加圧ローラ５３０と、加圧ローラ５３０に当接して回転駆動する定着ベルト５１０との間で記録用紙Ｐ上の未定着画像を記録用紙Ｐ上に定着させる定着装置５０であって、記録用紙Ｐのジャムの発生の予兆となる特定のパラメータの変化を検出する予兆検出部５６と、ジャム発生の予兆となる特定のパラメータの変化が検出された場合、定着ベルト５１０の回転駆動を停止させる定着駆動制御部５８と、を備える。【選択図】図８
